Foot and Mouth Disease is a state-controlled disease and a serious animal health threat facing South Africa. This highly contagious viral illness affects cattle, sheep, and goats, disrupting farming and trade. Effective prevention and control are essential to protect livestock, safeguard farmers’ livelihoods, and strengthen the red meat industry.
What is Foot and Mouth Disease in Animals?
Foot and Mouth Disease (FMD) is a highly contagious viral illness that affects cloven-hoofed animals. It remains one of the most serious threats to livestock health in South Africa and worldwide. Key details include:
Animals Affected
- Cattle, pigs, sheep, goats, and some wild game species.
- Young animals (calves, lambs) are particularly vulnerable to high mortality.
Cause & Transmission
- Caused by an Aphthovirus that spreads quickly between herds.
- Transmission occurs through direct animal contact, contaminated feed, water, or farm equipment.
Symptoms
- Fever and reduced appetite.
- Painful blisters on the mouth, tongue, hooves, and teats.
- Lameness, weight loss, and a sharp decline in milk production.
Human Impact
- Foot and mouth disease does not infect humans, but it severely disrupts trade and farming operations.
- Outbreaks often lead to animal movement restrictions, trade bans, or culling.
By understanding these basics, farmers and stakeholders can prioritise early detection, vaccination, and strong biosecurity to protect animal health and safeguard livelihoods.

How Foot and Mouth Disease Affects Animals
Foot and Mouth Disease (FMD) has a direct and severe impact on livestock health, welfare, and productivity. Once animals are infected, the consequences can be long-lasting and economically damaging. Key effects include:
- Reduced Productivity
- Milk production drops sharply in dairy cows due to fever and mouth lesions.
- Weight gain in beef cattle slows, reducing overall growth and market readiness.
- Animal Welfare Issues
- Painful blisters on the mouth, tongue, and hooves make eating and walking difficult.
- Lameness often results, limiting mobility and increasing vulnerability to secondary infections.
- Mastitis in dairy cows, which results in culling.
- Impact on Young Animals
- Calves, lambs, and piglets are especially at risk, with higher mortality rates.
- Growth and development are stunted, reducing future productivity.
- Long-Term Health Effects
- Even after recovery, animals may suffer reduced fertility and ongoing weakness.
- Herd performance declines, requiring additional resources for recovery.
- Indirect Consequences
- Farmers may be forced to cull infected animals to stop further spread.
- Loss of valuable breeding stock disrupts herd development for years.
Overall, foot and mouth disease undermines both the health of animals and the economic security of farmers, making prevention and early control measures absolutely vital.

Economic and Industry Implications
Foot and Mouth Disease (FMD) does not only harm animal health; it also places enormous strain on the broader livestock industry and national economy. The main implications include:
Farmer Losses
- Reduced milk yields, lower weight gain, and animal deaths cut into profits.
- Culling of infected herds leads to immediate financial setbacks and loss of valuable breeding stock.
Trade Restrictions
- Outbreaks often trigger export bans on red meat and live animals.
- Loss of international market access undermines competitiveness and revenue.
Market Instability
- Domestic prices fluctuate as supply is disrupted.
- Consumers may shift buying behaviour due to safety concerns.
Value Chain Disruptions
- Abattoirs, feedlots, and transporters experience delays and reduced throughput.
- Rural communities relying on livestock income face economic hardship.
National Economic Impact
- Agriculture’s contribution to GDP weakens during prolonged outbreaks.
- Emergency disease control measures increase government and industry costs.
Ultimately, foot and mouth disease threatens both livelihoods and food security, highlighting why strict control and rapid response are essential for protecting the red meat industry.

How Foot and Mouth Disease Spreads Among Animals
Foot and Mouth Disease (FMD) is highly contagious, and its rapid spread makes it one of the most difficult livestock diseases to control. Transmission occurs through several pathways:
- Direct Animal Contact
- Sick animals spread the virus through saliva, milk, breath, and secretions.
- Herds grazing or drinking water together are at high risk.
- Contaminated Surfaces
- Farm equipment, feeding troughs, and water sources can carry the virus.
- Transport Vehicles and tools that move between farms often act as carriers.
- Human Movement
- Clothing, shoes, and hands of farmworkers or visitors can transport the virus unknowingly.
- Lack of biosecurity measures increases the risk of accidental spread.
- Animal Movement & Trade
- Moving infected animals across regions or borders rapidly spreads the disease.
- Informal or uncontrolled markets increase exposure.
- Environmental Persistence
- The virus can survive for weeks in soil, hay, and manure under cool conditions.
Because foot and mouth disease spreads so easily, strict quarantine, movement control, and hygiene practices are essential to stop outbreaks from escalating.

Prevention and Control Measures
Controlling Foot and Mouth Disease (FMD) requires a combination of strong biosecurity, rapid response, and long-term prevention strategies. Key measures include:
Quarantine & Movement Control
- Infected farms are isolated to stop further spread.
- Animal movement is restricted within Disease Management Areas.
Vaccination
- Strategic vaccination campaigns in high-risk zones reduce outbreaks.
- Regular booster doses help maintain herd immunity.
On-Farm Biosecurity
- Farmers must disinfect equipment, vehicles, and footwear.
- Limiting visitors and controlling herd contact reduces exposure.
Traceability Systems
- Digital platforms track animal movements and incidents in real time.
- Quick reporting ensures faster containment during outbreaks.
Government & Industry Collaboration
- Joint efforts provide resources for surveillance, testing, and farmer support.
- Coordinated communication ensures stakeholders act swiftly and consistently.
Through consistent application of these measures, the livestock sector can significantly reduce the risk of foot and mouth disease outbreaks and protect both animal health and farmer livelihoods.
